United States Patent 2,993,226 ADJUSTABLE STOP I-HNGES Charles H. Baker, Jr., and Elizabeth Baker, both of 4441 S. Dearborn, Melvindale, Mich. Filed Apr. 10, 1959, Ser. No. 805,614 2 Claims. (Cl. 115-191) This invention relates to improvements in hinges incorporating adjustable checks or stops, and more particularly to novel hinges of this kind wherein stops or checks are adjustably mounted on the pins.

The primary object of the invention is to provide hinges of the character indicated above wherein the checks or stops are removably and non-rotatably mounted on the opposite ends of the hinge pins, and are readily removable therefrom and replaceable at new angles around the hinge pins, without requiring dismantling of the hinges or the use of tools, so as to stop or check the hinge leaves at different desired angles relative to each other.

Another object of the invention is to provide simple and efiicient hinges of the character indicated above wherein stops or checks are provided at two points along the lengths of the pins for two-point engagement by leaves, so that the hinges have greater strength and sta bility and resistance to being strained or warped by engagement of hinge leaves with stops or checks, as where an associated door is swung open with force, without sub stantial increase in the weight, bulk, or cost of the hinges.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

FIGURE 1 is a perspective view of one form of the invention, shown mounted to a door jarnb and a related door in open position;

FIGURE 2 is an enlarged horizontal section taken on the line 22 of FIGURE 1;

FIGURE 3 is an enlarged vertical transverse section taken on the line 33 of FIGURE 1; and

FIGURE 4 is an enlarged perspective view showing the components on the scale of FIGURE 1.

Referring in detail to the drawings, wherein like and related numerals designate like and related parts throughout the several views, and first to FIGURES 1 to 4, the hinge therein shown and generally designated 12, comprises a swingable hinge leaf 14, a relatively stationary hinge leaf 16, a hinge pin 18, and a stop assembly 20.

The swingable leaf 14 is in the form of a flat plate 22 having screw holes 24 therein, and having hinge pin barrels on its inward edge 26, here shown as being two barrels 28 spaced along the edge 26, and having smooth bores 30 therethrough.

The stationary leaf 16 is in the form of a flat plate 32, having screw holes 34 therein, and having hinge barrels on its inward edge 36, here shown as being three barrels spaced along the edge 36, between which the hinge pin barrels of the swingable leaf 14 are interdigitated. It will be understood that different numbers of hinge pin barrels can be provided on the hinge leaves, it being essential, however, in the case of the stationary, leaf 16, that its barrels include end barrels 38 at the ends thereof. Here shown is an intermediate barrel 40 in line with the end barrels 38.

The side walls of the hinge pin barrels 38 of the stationary leaf 16 are formed to provide radial lugs 44 which project inwardly into the otherwise smooth bores 46 of these barrels. As shown in FIGURE 2, the lugs 44 are produced by indenting at least one side and pref- ICC erably diametrically opposite sides of the side walls of the barrels at points intermediate their ends, and the lugs 44 are dome-like in shape. The lugs 44 constitute one form of means, present in all forms of the invention, as hereinafter described, for securing a hinge pin 18 nonrotatably in the barrels of the stationary leaf 16.

The hinge pin 18 comprises a cylindrical portion 48 of a length to extend through the barrels of both hinge leaves, which has polygonal axial extensions 50 on its ends, serving as mounting means for stops or checks, as hereinafter described, and which reach beyond the outer ends of the end barrels 38 of the stationary leaf 16. The cylindrical portion 48, on which the barrels 28 of the swingable leaf 14 freely turn, can be smooth surfaced, except for recesses or indentations 52 which are formed to receive related lugs 44, whose engagement in the recesses 52 secures the stationary leaf 16 and the hinge pin 18 together, and against rotation relative to each other. In this arrangement, the barrels of the stationary leaf are preferably made yielding and resilient, so that the pin 18 can be forced through the barrels, and the lugs become seated in the recesses.

The stop assembly 20 of the hinge 12 comprises the polygonal hinge pin extensions 50, here shown as being hexagonal, and related stops or checks 54. The stops 54 are similar in construction but are reversed in position. Each stop 54 comprises a cap 56 having a polygonal socket 58 in its rearward end 60 to conformably and frictionally receive a related extension 50, so as to be removable from the extension but ordinarily held thereon by friction or other suitable means.

The sockets 58 are preferably axial in the steps 54 and the caps 56 are substantially larger in diameter than the pin 18 and the end pin barrels 38. Fixed to and extending from the inner ends 60 of the cap and concentric with the sockets 58 are stop lugs 62 which are preferably arcuate and having free inner edges 64 which extend inwardly beyond the outer edges 66 of the end barrels 38, as apparent in FIGURE 3, and have end edges 68 and 70. The end edge 70 is arranged for stop engagement by the related side of the swingable hinge leaf 14, in fully or partially open position of such as a door 72, on whose edge the swingable leaf 14 is secured, as by screws 74, with the stationary leaf 16 secured on the edge of the associated door jamb 76, as by screws 78.

Adjustments of the stop assembly 20, to provide for stopping of the swingable leaf 16, and the door 72 in selected open positions, is achieved by removing the stops 54 from the pin extensions 50, and then restoring the same on the extensionsin other and different angular positions, so that the stop lug end edges 70 are located to stop the door in the desired open position. These adjustments can be conveniently done by putting the door in the desired position and then removing the stops from the pin and replacing them thereon, with their stop edges 70 against the related side of the swingable leaf 16.

What is claimed is:

1. An adjustable stop hinge comprising a hinge pin having ends, a relatively stationary hinge leaf, a swingable hinge leaf, said leaves having inward edges having interdigitated hinge barrels thereon receiving said hinge pin, the barrels of the swingable leaf being freely journaled on the hinge pin, means connecting barrels of the stationary leaf and the hinge pin together against relative rotation, and a stop assembly comprising a component mounted on each end of the hinge pin, each component having a stop element projecting into the path of swing of the swingable hinge leaf, and means mounting the said components of the hinge pin ends for adjustment to different angular positions relative to the hinge pin, said connecting means comprising recesses in the hinge pin and logs on barrels of the stationary leaf engaged in said recesses.

2. An adjustable stop hinge comprising a hinge pin having ends, a relatively stationary hinge leaf, a swingable hinge, leaf, said leaves having inward edges having interdigitated hinge barrels thereon receiving said hinge pin, the barrels of the swingable leaf being freely journaled on the hinge pin, means connecting barrels of the stationary leaf and the hinge pin together against relative rotation, and a stop assembly comprising a component mounted on each end of the hinge pin, each component having a stop element projectinginto the path of swing of the swingable hinge leaf, and means mounting the said References Cited in the file of this patent UNITED STATES PATENTS 411,152 Kuhn Sept. 17, 1889 431,078 Russell July 1, 1890 1,060,641 Sladden May 6, 1913 2,843,873 Slower July 22, 1958
